Cars facing the punishing climate and sand of the Omani desert stay lubricated with Shell Oman’s full synthetic Helix Ultra SAE 0W-20. The low-viscosity oil provides wear and corrosion protection and defends components from high stress and extreme temperatures. It is also designed to mitigate the effects of low-speed pre-ignition on small, turbocharged direction injection engines, the company adds. Helix Ultra meets the API SN Plus passenger car motor oil standard. Web: www.shelloman.com.om
